Title: Cold strip mill working roll surface temp control - - by means of pyrometers and cooling oil spray nozzles
IPC: B21B27/10
Filed: 1971-11-30
Abstract: The cross sectional thickness of metal strips being cold rolled is monitored esp. controlled by the monitoring of the working roll surface temp. along their length, which data are used to exert a cooling action on the relevant roll surface sections to obtain a laid down temp. distribution along the roll surface. In the prefd. design a number of pyrometers are arranged parallel to each other along the rolls. These feed their findings to a controller which controls the corresp. cooling oil spraying nozzles. By correct adjustment of the roll surface temp. the stresses applied to the metal strip conform to an optimum pattern resulting in uniform deformation of the strip and hence more uniform thickness.

Patent FR-2261602-A1 (FR)
Title: Composite magnetic relay elements - is particularly for relays and circuit breakers and provides mechanical protection and fast release
IPC: H01H50/16
Filed: 1974-02-19
Abstract: The design for relay elements has the magnetic armature or mobile part made up of the magnetic element itself and carrying a nonmagnetic slip. Such moving items in relays and contactors are subject to strong mechanical shocks as they move from energised to de-energised states. Also due to remnant magnetic effects a neat, clean break does not occur on de-energising the coil. To overcome these effects a high reluctance gap is established by including on the soft iron armature an alloy such as bronze in the form of a 0.03 to 0.50 m.m. insert at any suitable position on the armature.

Title: Liq. crystal cell controller and visual panel - incorporates triacs connected to system supplying logic information as binary signals
IPC: G09G3/36
Filed: 1974-03-29
Abstract: A device for controlling a liq. crystal cell with two electrodes incorporates an exciting circuit with a first and second branch bringing about polarisation of the electrodes, a system supplying logic information in the form of binary signals, and a semi-conductor commutator, e.g. a triac, in each branch of the circuit receiving the information on its control electrode and bringing about the closing and opening of the corresponding branch. The exciting circuit includes a source of alternating voltage and resistance bridges which act as potential dividers. A visual panel incorporating the control device incorporates a matrix of liq. crystal cells with "line" and "column" terminals, one branch of the control circuit being associated with each "line" terminal and a second branch being associated with each "column" terminal. The system is applicable to all systems necessitating an extinction and gives an appreciable reduction of cost compared to conventional systems.

Title: Loom with Jacquard control has auxiliary weft pickers - to insert fibre rovings into shed to produce tassels along edge of fabric
Inventor: TILLON GEORGES
IPC: D03D35/00
Filed: 1975-03-20
Abstract: A loom is controlled by a lacquered mechanism and has a series of auxiliary weft pickers which insert rovings into the edge of the warp to form tassels along the edge of the woven fabric. Each auxiliary weft picker is in the form of a rod extending radially from a control shaft which can be moved longitudinally and also rotated, so that limited rotation and of the shaft during picking allows the rovings to be twisted around each other. The mechanism allows a loom to be easily modified to produce fabrics with tassels along its edges.
Patent FR-2267172-A1 (FR)
Title: Cores for foundry moulds - made of carbonized fibre mats reinforced by synthetic resin impregnation
IPC: B22C9/10
Filed: 1975-04-11
Abstract: A core for foundary moulds consists of porous carbonized material, made of wool, cotton, rayon or polyacryl nitrile fibres which have been turned into carbon by heating in an inert or reducing atmosphere to 800-1200 degrees C. Further reinforcement can be achieved by impregnation with an artificial resin. This eliminates the fractures caused by shrinkage stresses when complex cores made of plastic foam are carbonized. Even complicated or hollow cores can be produced without loss of material.

Title: Smoke reduction system for furnace - has dust precipitator with precipitator and fluidised bed from which particles reenter furnace
Inventor: REBOURS ALBERT
IPC: F23C9/06
Filed: 1975-12-10
Abstract: A furnace (1) has its products of combustion led to a precipitator (5). The gases leave via a chimney while the solids collect in a hopper (6).

Title: Mfr. of sailing masts from blank sheet - has material folded round tapered mandrel with edges of sheet held by series of screws
IPC: B21C37/10
Filed: 1976-06-01
Abstract: Manufacture of sailing masts from a blank (15) of sheet metal starts with a mandrel (22) being pressed down by a screw (31) onto the sheet, which rests on a hollowed wooden base (24). This forms the blank into a 'U' section, and the screw is then removed. For the next stage a long screw (38) is inserted through previously drilled holes at the top of the 'U' section and formers (36) and nuts (39). As the nuts are tightened the 'U' section is closed cover the mandrel. The screws are removed and the mandrel which like the must is tapered, is withdrawn. The excess flanges (43, 43') are then cut off to leave the completed mast.
